‘Entirely open’

Oxfam International’s executive director Winnie Byanyima said that Mr Fuentes had been “entirely open with his Oxfam board”.

“He has assured us that he has co-operated fully with the investigation in the confidence he did not knowingly transgress rules or procedures,” Ms Byanyima said.

It comes as Oxfam faces scrutiny over a scandal in Haiti in 2011, where senior aid workers – including the country director Roland Van Hauwermeiren – allegedly paid for sex. Some of the claims say the women may have been underage.

In Guatemala, Mr Fuentes is among 10 top former government officials arrested on Tuesday, including former President Álvaro Colom.

The ex-officials are being investigated in connection with a public bus system, which was developed during Mr Colom’s government between 2008 and 2012.

No details have been given of the charges those arrested may face.

The investigation is being led by the International Commission against Impunity in Guatemala (CICIG). The commission is a United Nations body created in 2006 designed to strengthen the country’s rule of law.

Ex-leaders in the spotlight

Apart from Mr Colom, those arrested are the former ministers of finance, interior, education, defence, employment, economy, health, culture and the environment.
